Honeywell JetWave X Satcom Terminal Enters Service With Up to 300 Mbps Global Ka-Band Coverage
Why It MattersThe terminal shows business-aviation connectivity shifting from single-orbit hardware to multi-orbit, software-routed service, so equipment lifecycles increasingly track the satellite operator's network roadmap rather than a one-time antenna purchase.
What happened
Honeywell Aerospace announced on Oct. 20 that its next-generation JetWave X broadband satellite communications terminal has entered into service. The terminal supports download speeds of up to 300 Mbps with global coverage and connects to Viasat's Ka-band network, including the new ViaSat-3 and former Inmarsat Global Xpress geostationary Earth orbit (GEO) satellites. Honeywell says its open architecture is designed to take advantage of the network's continued growth as future satellites enter service.
Honeywell originally provided JetWave terminals as an equipment supplier and value-added reseller for Inmarsat, before Viasat acquired Inmarsat in 2023. Viasat has branded its inflight broadband service for business aviation as JetXP, and plans to integrate Telesat Lightspeed low Earth orbit (LEO) satellite capacity by late 2027 as part of a multi-orbit strategy for JetXP. Claudio D'Amico, Viasat vice president for business aviation, said JetWave X is the first terminal able to use the full network, including the fully operational ViaSat-3 constellation.
The terminal features data control routing software that supports Ka-band transmission over both GEO and LEO networks and directs traffic over the optimal link based on application requirements. Latency-sensitive applications such as video conferencing are routed through the lower-latency LEO network. The software also enables packet duplication over both links, maintaining service if one connection is interrupted.
Honeywell says upgrading to JetWave X is fast and affordable because in most cases the terminal uses existing Ka-band radomes and wiring. Legacy JetWave customers have a trade-in program. Honeywell advises operators to check the supplemental type certificate status for their aircraft to understand certification availability and installation readiness.
Industry impact & what to watch
The more consequential change here is architectural. A terminal that decides, packet by packet, whether traffic travels over GEO or LEO moves part of the value from the antenna to the routing software, and ties the hardware's usefulness to what the network operator adds around it. For owners of aircraft already carrying Ka-band equipment, that makes the satellite roadmap, not the terminal's own specification, the main variable in how long an installation stays current.
Reuse of existing radomes and wiring matters for the same reason. In business aviation, the cost and downtime of opening up an airframe usually weigh as heavily as the equipment price, so an upgrade path that avoids new structural work lowers the barrier to moving fleets onto a new network, and the trade-in program extends that logic to legacy JetWave customers.
The milestone to follow is the one already on the calendar: the planned Telesat Lightspeed LEO integration into JetXP by late 2027, which is when the LEO routing capability described for the terminal would come to matter in practice. Aircraft-specific supplemental type certificate status, which Honeywell itself points operators to, will determine how quickly installations can follow.
